Abstract

The invention relates to a computer control system for a novel direct drive lockstitch sewing machine. The computer control system comprises a master controller, a pedal speed regulator, an operation panel, solenoid valves, a power supply module, a motor, a motor drive controller and a photocoupling isolation module. The computer control system is characterized in that the master controller consists of a microprocessor CPU, a communication module, a driving module for the solenoid valves, a speed control module and a current control module; the microprocessor CPU realizes bi-directional data communication with the operation panel by a communication module circuit, realizes control and protection over actions of the solenoid valves of the sewing machine by a solenoid valve drive circuit, and realizes variable frequency control over the motor by the speed control module and the current control module; the master controller is respectively connected with the pedal speed regulator, the operation panel, the solenoid valves and the photocoupling isolation module; and the motor drive controller consists of a special servo drive module and a current detection module.

Description

1. Technical field [0001] The invention relates to a control system for controlling the operation of an industrial lockstitch sewing machine, in particular to a novel computerized control system for a direct-drive lockstitch sewing machine. 2. Background technology [0002] After nearly 60 years since the founding of the People's Republic of China, especially the development of the reform and opening up in these years, China's sewing machine industry has achieved remarkable achievements. However, in terms of research and implementation of computer control systems to improve the high-tech level of sewing machines, it has always been in a backward state. It was not until the end of the 1990s that Chinese enterprises began to develop the computer control system of the three-belt pulley automatic lockstitch sewing machine. At the beginning of this century, in order to continue to maintain its leading position in product technology, Japan launched a new type of direct-drive oil-...
